Gum laced with a plant-grown protein is found to reduce COVID-19 transmission by 95% after trapping and neutralizing the virus in the person's saliva, Penn State University scientists find
- The cinnamon-flavored gum is infused with ACE2, which is a plant-grown protein
- The protein traps the virus in the saliva and then neutralizes it
- Testing of the gum shows this innovation can reduce transmission by 95%
A team of scientists led by Penn State University infused gum with a plant-grown protein and found it 'traps' the SARS-CoV-2 virus.
The protein, known as ACE2, prevents the virus from attaching to a host cell in the human body by interacting with SARS-CoV-2's receptor binding domain - this facilitates virus attachment to the receptor and fusion with cell membrane.
Gum with a plant-grown protein reduces COVID-19 transmission by 95%
The cinnamon-flavored gum was infused gum with a plant-grown protein, known as ACE2, which 'traps' the SARS-CoV-2 virus in a person's saliva and then neutralizes it to stop transmission.To test the chewing gum, the team grew ACE2 in plants, paired with another compound that enables the protein to cross mucosal barriers and facilitates binding, and incorporated the resulting plant material into cinnamon-flavored gum tablets. Incubating samples obtained from nasopharyngeal swabs from COVID-positive patients with the gum, they showed that the ACE2 present could neutralize SARS-CoV-2 viruses.
